Brontoscorpio

Machine-translated from the Spanish article

Brontoscorpio anglicus ("English thunder scorpion") is an extinct genus and species of aquatic scorpion one meter in length that lived during the Devonian period in the British Isles. Its remains were discovered in sandstones of the Upper Silurian of Trimpley, in Worcestershire, and the species was described based on a single appendage of a pedipalp almost 10 centimeters long. It has been estimated that the complete animal must have measured at least 90 centimeters in length.
